Ready to suspend your brain cells in a superposition of disbelief? Good, because the latest news published in Nature is that diamonds are a quantum computer's best friend -- particularly if they're flawed. An international team of scientists sought out sub-atomic impurities in a 1mm-thick fragment ...

Technology's holy grail is the development of a "perfect" Quantum Computer. Traditional computers recognize information as bits: binary information representing "On" or "Off" states. A quantum computer uses qubits: operating in superposition, a qubit exists in all states simultaneously -- not just ...

Transistors -- the basic building block of the complex electronic devices around you. Literally billions of them make up that Core i7 in your gaming rig and Moore's law says that number will double every 18 months as they get smaller and smaller. Researchers at the University of New South Wales may...

We're big fans of quantum computing, and hopefully it's about to get a lot more reliable. Researchers at Yale have demonstrated quantum error correction in a solid state system for the first time. Quantum bits were created from "artificial" atoms using superconducting circuits, these qubits are the...

Got your wire-rimmed spectacles on? Had a full night's rest? Eager to get those synapses firing? Here's hoping, because Marc Cheneau and co. are doing everything they can to stretch the sheer meaning of quantum understanding. The aforesaid scientists recently published an article that details a meth...

This should come as a great relief to anyone planning a quantum computer self-build: wires still conduct electricity and obey key laws of classical physics even when they're built at the nanoscale. Researchers at Purdue and Melbourne universities used chains of phosphorus atoms inside a silicon c...

Did you know that light is a better transmitter of quantum computer information than any sort of cabling? Because it isn't altered by electric and magnetic fields, it would be perfect for carrying data if photons would stop being so snobby and interact with one another. Only highly-sensitive in...

Quantum Computers already exist, but not in the "universal" form that would truly revolutionize computing. That's why the latest innovation from Bristol University has so much promise: a team from its center for Quantum Photonics has built a reprogrammable quantum chip. The 70mm x 3mm box is ca...

Notoriously difficult to pin down, electrons have always been free spirits -- until now that is. According to a paper published by science journal Nature, folk at Cambridge University much cleverer than we have tamed single electrons, succeeding in coaxing them directly from point-to-point. The...

Quantum computing has a long way to go before becoming truly mainstream, but that certainly hasn't stopped us from indulging in dreams of a qubit-based existence. The latest bit of fantasy fodder comes from the University of California, Santa Barbara, where researchers have become the first to combi...

These guys aren't Purdue University professors, they're DJs. That thing on the left? It isn't a high-mobility gallium-arsenide molecular beam epitaxy system, it's their decks. It creates an ultra-pure material so perfectly latticed that it traps electrons between its layers and stops them bouncin...

Who found ten million dollars to drop on the first commercially available quantum computer? Lockheed Martin, it seems, as the aerospace defense contractor has just begun a "multi-year contract" with the quantum annealing experts at D-Wave to develop... nothing that they're ready or willing to pub...

Whether or not D-Wave has actually built a quantum computer is still a matter of debate (though, a study authored by the company and published in Nature claims to prove its success) but, whatever it is these crafty Canadians have created, you can order one now and start crunching qubits with aban...

Okay, so we might be chasing the flying unicorn of modern technology here -- and, no, we're not talking about the white iPhone 4 -- but as you've probably noticed, our hunger for a quantum computer is basically insatiable. Lucky for us, some folks who actually know something about producing qubits ...

We are totally ready for a quantum computer. Browse the dusty Engadget archives and you'll find many posts about the things, each charting another step along the way to our supposed quantum future. Here's another step, one that we think is a pretty big one. An international team of scientists has m...

Quantum anything has typically fallen into our oft-used category of 'awesome things that'll never happen,' but if a crew of researchers at the California Institute of Technology have anything to say about it, they'll soon be changing the fortunes of that segment. The team has recently demonstrated q...

Another day, another step bringing us closer to the next big revolution in the world of computing: replacing your transistory bits with qubits. Researchers at Australia's Universities of New South Wales and of Melbourne, along with Finland's Aalto University, have achieved the impossibly tiny goal ...

You know the drill -- some quirky research team whips up some phenomenal discovery in the middle of nowhere, gloats about it, gets it published in a journal you've never heard of it, and then it all vanishes into the ether, leaving your soul hurt and wondering why you ever got your hopes up in the ...

The quantum computer is still ranking pretty high up there on the vaporware charts, somewhere between Duke Nukem Forever and a Steorn in-home power generator. Eventually we'll get there, and theoretical physicists at the University of Bristol are helping with a quantum cooling system. It is effecti...

Physicists at Johannes Gutenberg University in Germany are developing something which they call the Mainz interface, and which could eventually lead to a quantum computer -- a whole new way of communicating information. For now, though the Mainz interface is seeking to use laser light traveling thr...
